Testing Standard:
TAPPI T411 Thickness (Caliper) of Paper, Paperboard, and Combined Board
Standard Number
TAPPI T411
Standard Title
Thickness (Caliper) of Paper, Paperboard, and Combined Board, Test Method
Overview:
TAPPI T411 Test Method is the measurement of a single sheet thickness of paper and corrugated material. With thickness directly related to the flexural properties of a fiberboard shipper, it is important to verify the caliper to identify potential issues in the overall strength of the packaging materials. Purple Diamond Testing offers TAPPI T411 Thickness (Caliper) of Paper, Paperboard, and Combined Board as part of our packaging compliance and validation services.
Rationale:
TAPPI T411 – Thickness (Caliper) of Paper, Paperboard, and Combined Board. Data is obtained using a standard constant pressure for all materials being evaluated to ensure an accurate measurement across all material types. The data obtained can be used to verify manufacturer specifications, compare different materials, and aid in design.
Key Points:
- Correlates to other paper characteristics, such as TAPPI T403 for bursting strength
- Crucial when designing corrugated packaging
- Utilize this test method to ensure quality control
Related Standards:
